HEATING APPABATUS.

Specficaton of Letters Patent. V Patgnted Feb. 17 1914,

V Application filed June 10, 1913. Seri'al No. 772,787.

To aZZ whom it may concern Be it known that we, "WILLIAM CHECK andBURRELL IVAN SIPES, citizens of the United States, residing at BuenaVista, in the county of Chaffee and State of Colorado, have inventedcertain new and useful Improvements in Heating Apparatus, of which thefollowing is a specification.

The present invention relates to heating apparatus and has for itspurpose to provide a construction whereby the maximum heating eificiencyis obtained to the end'of economy in the maintenance of the system; andwherein a snialler apparatus may be used to obtain a given result thanis possible with any of the heating apparatus at present in use.

The invention has for its further purpose to provide a heating apparatusadapted for use in connection with radiator heating systems, incubatorshot houses for floral culture, and steam heaters generally; and whereinthe heating medium employed may be either electricity, gas, coal or oil.

The invention further contemplates an apparatus for generating heatwhich will not readily get out of order, and which may be manufacturedand installed at comparatively small cost.

With these and other objects in view the invention consists in the noveldetails of construction and combination of parts more fully hereinafterdescribed and particularly pointed out in the claims.

The invention is shown by way of illustration in the accompanyingdrawing which discloses an elevational view of the apparatus complete,and partly broken away for clearness.

Referring to the construction in further detail 1 designates the boileror inner casing which is surrounded by a jacket or outer casing 2providing a dead air space or vacuum chamber 3. An inner casing i ismounted centrally within 'the boiler 1 and provided with the combustionchamber 5, which is open at the bottom 6 to receive the burner 7 thatcommunicates with the source of fuel supply through the pipe 8.

It is to be understood of course that any desired form of heater andkind of fuel may be used.

The inner casing 4 is closed by the top 9 and an outlet pipe 10 securedto said top communicates with the combustion chamber and provides themeans for carrying ofl the products of combustion. A baifle 11 islocated immediately beneath the Opening of r the pipe into thecombustion chamber and serves to retard or interrupt the flow of the hotgases as will be readily understood.

The boiler 1 is adapted to be filled through the pipe 11 having a funnel12, and said pipe 11 is provided with an ordinary controlling valve 13.The pipe 14 serves as an outlet for the boiler, and said pipe is alsofitted with a controlling valve 15. An ordinary gage glass 16 isprovided for ascertaining the level of the water X within the boiler.

An outlet pipe 17 leads from the heating chamber 18 of the boiler and isadapted for conducting the hot air or steam vapors to the place or pointto be heated. And said outlet pipe 17 is provided with an outer' casingor covering pipe 19 forming the chamber 20, likewise adapted to providea dead air or vacuum space and which communicates with the space 5surrounding the boiler. From the place of delivery the condensed steamvapors o-r heated gases which are reduced in temperature, are returnedto the generating chamber 18 of the boiler through the pipe 21 thatenters the chamber 18 at approximately the point 22 just above the levelof the water. Said return pipe 21 V is in like manner inclosed orsurrounded by a pipe 23 to provide a dead air space or vacuum chamber 24as clearly shown in the drawing.`

A controlling valve 25 is mounted in the pipe 21 and is adapted forshutting off the return passage therethrough should the same be desired.In this event the returning gases or vapors would be permitted to escapethrough the cock 26 which is mounted on said pipe just above theregulating valve 25. A pipe 27 having a controlling valve 28 is mountedon the return pipe 21 at the elbow 29 thereof, and communicates with thechamber 18 through the passageway in said pipe elbow. The pipe 27 isadapted to communicate with the source of air supply under pressure oran air generator for the purpose of ejecting air into the generatingchamber 18 for accelerating the passage of the steam or hot air fromsaid chamber 18 through the pipe 17 to the place desired to be heated.

From the foregoing it willbe readily seen that the heating apparatusdisclosed herein consumes the maximum heating efficiency of the tuel byavoiding heat radiation 2 e., the heat which is ordinarily radiated fromthe generator by reason of the absence of the surrounding dead air spaceor vacuum. And in like manner the steam or hot air is maintained at hightemperature since there can be no beat radiation by reason of the vacuumchamber or dead air space surrounding the conducting pipes 17 and 21.

It is Obvious that those skilled in the art may vary the details ofconstruction and arrangement of parts, without departing from the spiritof our invention and therefore we do not wish to be limited to suchfeatures except may be required by the claims.

l/Vhat we Claim as new and desire to protcct by United States LettersPatent is l. In a heat generating apparatus the combination of a vesseladapted to hold water and providing a heating chamber, and having acombustion chamber therein open at the bottom; a casing surrounding saidvessel and leaving a space therebetween to form a vacuum chamber; anoutlet pipe leading from the heating chamber; a. casing surrounding saidpipe and providing a vacuum chamber; an inlet pipe leading into theheating chamber; a casing surrounding said inlet pipe and providing avacuum chamber; and a burner located in said combustion chamber;substantially as described.

2. In a heat generating apparatus the combinaton of a vessel adapted tohold water and providing a heating chamber, and constructed with acombust-ion chamber open at the bottom; a casing surrounding said vesseland providing a space to form a vacuum chamber; an outlet pipe leadingfrom said heating chamber; a casing surrounding said outlet pipe andproviding a space to form a vacuum chamber; a pipe leading into saidheating chamber; a casing surrounding said inlet pipe and providing aspace to form a vacuum chamber; a shut off Valve and an outlet valve forsaid inlet pipe; a pipe leading into said inlet pipe adapted tocommunicate with a source of fluid under pressure; a. burner located insaid combustion chamber; and an outlet pipe leading from the combustionchamber substantially as described.

In testimony whereof we aiiix our signatures in presence of twowitnesses.
